I don’t have any knowledge about transferring but I do wonder if the New England winter isn’t weighing on you. Coming from Texas, you can’t underestimate this. The isolation, gray skies, and cold can be so difficult. With study abroad as an option, personally, that is what I would focus on. Go somewhere where you can enjoy a metropolitan area (and some better weather!) I think if you can just get through Feb and March, the weather (and I realize it is not just the weather but I wonder if it doesn’t really play a big factor) will look up. If you decide to study abroad, if you could pore yourself into finding a program and getting amped up for it, that would be my advice.
The people who matter in medschool admissions know about Williams; I realize telling you that it is an extraordinary school with a fantastic reputation doesn’t change how you feel right now, but that is its reputation for the people making medschool decisions.
Finally, don’t neglect your mental health. Back to the isolation and the weather; SAD is real. Some proactive measures can go a long way to help.
But ultimately, you only live one life and need to do what feels right in your gut. I would concur that you need to cast a wider net if you go for transfers as - just like college admissions - there are no guarantees and just applying to reach schools is a recipe for disappointment. I do, however, feel that applying to disparate types of schools is just fine. I know my daughter is quite interested in Brown for it’s open curriculum as well as Cornell for a certain major. We live near Brown so she is quite familiar with it. I hope you update this thread and let us know what you decide. I just wanted to say good luck and this stage will eventually pass, no matter what you do.
